Can ghosts attach themselves to you and follow you to a different location?

i had a ghost in my old home but it was a little girl but she was very disturbing at times. she got attached to me because she would color in front of my door if i put crayons and a book out there. and without me noticing she would sometimes hum a very low low sound but if you listen you could hear it. and there was a time were a pencil was thrown at me when no one was around. i did move to a different house and now there will be someone knocking at my bedroom door and i would look and no one was there and i would see shadows when there were no lights on and the kitchen light would turn on occasionally... but if this is a ghost they would never enter my room i have never noticed them in any room but the living room hallway and kitchen... i also have a bruise on my right bottom part of my leg and u can perfectly put your first three fingers were the marks are and the kinda match depending on the size of your fingers am i imagining this? or could something have followed me to my new home?
